Sleep Apnea Treatment Can Help Control Diabetes

We know that sleep apnea increases your risk of diabetes. We also know that sleep apnea can make it harder to control your blood sugar levels if you have diabetes. But now a new study shows that treating sleep apnea can help you get your blood sugar levels under control and potentially help you avoid some of the more serious consequences of diabetes.

A Randomized Clinical Trial

Researchers conducted a randomized clinical trial to determine whether sleep apnea treatment with CPAP would improve patients’ ability to keep their blood sugar levels under control. They believe that this is the first time anyone has conducted this type of experiment — considered the gold standard for evidence of treatment effectiveness — on sleep apnea and diabetes.

Researchers took 50 individuals who had both obstructive sleep apnea and poorly controlled diabetes, then randomly assigned them to receive either CPAP or no new treatment. Unless changes were necessary for medical reasons, diabetes patients were expected to keep taking the same medication, eating the same diet, and following the same exercise regimen. After three and six months, patients were tested for glucose control, insulin sensitivity and resistance, inflammatory proteins, and other markers of diabetes.

Researchers saw several statistically significant improvements in patients using CPAP, including:

  • Lower blood sugar levels
  • Higher insulin sensitivity
  • Lower insulin resistance

In addition, they saw reduced concentrations of inflammatory molecules and an increased concentration of adiponectin, a hormone that helps regulate glucose levels, though these changes were not statistically significant.

Researchers noted some limitations in the study. First, the sample size is small. And there was no placebo treatment. Despite the attempt to keep diabetes treatment the same, some patients had to change for medical reasons.

A CPAP Alternative

Another limitation of the study is that it only looked at sleep apnea treatment with CPAP. Although CPAP is a highly effective treatment, and the one that doctors are most likely to prescribe, it’s not well tolerated and many people are looking for an alternative treatment.

Fortunately, there is an alternative to CPAP: oral appliance therapy. Oral appliance therapy for sleep apnea can be just as effective as CPAP, and many people find it more comfortable and convenient.
